2019 BMW Z4
Ratings & Reliability
After a three-year hiatus, a larger, more powerful BMW Z4 roadster returns to market with a soft top and reduced weight. The Z4 launches with the sDrive30i, and a high-performance M40i will be added later. Both versions have more power than before. Each uses an eight-speed automatic transmission. There is no more manual transmission option. The soft top can open and close when the roadster is on the move, which is a big convenience. The latest iDrive control system has a learning curve, but should prove logical after some familiarity. Owners can use a smartphone as a digital key. All Z4s are equipped with forward collision warning with pedestrian detection, automatic emergency braking, and lane departure warning.
